PRIMING AND TESTING CUP.

Specification of Letters Patent.

Patented J an. 13, 1920.

Application filed November 8, 1917. Serial No. 200,869.

To all whom it may concern:

Be it known that I, OSCAR A. SMITH, a

' citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Priming and Testing Cups, of which the following is a specification.

This invention relates to priming and testing cups for gas engines, the object of the invention being to provide an improved cup having all the advantages of the cups described in my United States Patent No. 1,153,457 dated September I I, 1915 and in my contemporaneously pending application filed October 80, 1917, Serial No. 199,252, and having, however, the further and important advantage that it can be used with motors that are located at an angle such as eight-cylinder and twelve-cylinder motors or inserted at the side of the motor wherever this is desired.

The cups shown in the patent and application referred to would necessarily have to be inserted into the motor casing at the top thereof, since if the cup was located at an angle or at the side of the motor, it would not be practicable to insert the fluid into the cup as it would run out before the valve was opened. It is oftentimes desirable, however, to insert these cups at the side of an engine or into motors located at an angle, and in order to permit this to be done successfully, I provide an improved cup having all the advantages set forth in the said patent and application hereinbefore referred to, while having the further advantage of enabling the cup to be used in a V-shaped motor or to be inserted in the side of the engine as may be found desirable in practice.

In the drawings accompanying and forming part of this specification,

Figures 1, 2 and 3 illustrate vertical sectional views of different styles of this improved cup, Fig. 1 illustrating in dotted lines, the cup partly open and illustrating the cup portion made as an integral structure as shown in my prior patent, while Figs. 2 and 3 illustrate the up as comprising a body made of bar stock and a cup portion of sheet metal and connected with the body in any desired way; Figs. 4, 5 and 6 are top views respectively of the cup shown in Figs, 1, 2 and 3; Fig. 7 is a top view of the b y portion of the cup sho n, for instance,

in Fig. 2; and Fig. 8 is a vertical sectional I view of the cup shown in Fig. 2.

Similar characters of reference indicate corresponding parts in the several figures of the drawings.

In the present improvement, like that shown in my prior patent and application, the valve is maintained closed by pressure thereon. Moreover by reason of the construction the carbon and soot cannot close or clog up the opening or passageway, since any that forms on the valve is fractured when the valve is opened as the valvepassage, by reason of the manner in which the valve opens and closes, is entirely out 01f from the combustion chamber of the engine and moreover by means of the present construction, the valve is proof against leakage so that it is'always possible to easily manipulate the valve without liability of the carbon injuring the valve seat or valve, and thus the valve can always be maintained tightly seated and so prevent any possible loss of power resulting from an imperfect seating of the valve.

In my prior patent, the priming cup was made in tWo parts; in my prior application it was made in three; in the present improvement it may be made in either two parts as shown in Fig. 1 or in 3 as shown in Figs. 2 and 3. When made in the manner shown in Figs. 2 and 3, the body portion of the cup may be made from a block or bar stock and the cup portion of sheet metal, as brass or steel, and preferably drawn therefrom so that the body portion may be made upon an automatic screw machine and the parts assembled in some suitable way, as by threading one on to the other as shown in Figs. 2 and 3, or by spinning or 'peening one part on to the other as shown in my prior application, or in any other desired way. This of course permits the cup portion to be drawn out of sheet metal of any size and design desired, so that the cup portion may be made cheaper and of different designs or sizes, as the cost of drawing the cup of sheet metal and assembling it to the body would be considerably less per cup than to make the cup of an integral structure of brass upon an automatic screw machine. The present improved priming and testing cup, while particularly adapted for gas engines, may of course be used for various purposes. When made as an integral structure it comprises a body portion 2 and a cup portion 6 made from a single piece of stock exteriorly threaded at one as the lower end i -which threads in the present instance are shown as of the tapered variety, although a straight thread could be used,for insertion into the engine and provided with a wrench-receim ing portion 5 and a cup portion 6 located at an angle to the body portion. The body portion is drilled to form an axial passage 7 having interior threads 8 for a part of its length. Formed lengthwise of the body and shown in the present instance as extending therethrough is one or more openings shown herein as grooves or slots 9, preferably two in number, which slots in the present instance open into the axial passageway. Obviously the openings 9 might be simply holes drilled through the body and opening into the axial passageway at the lower end there of adjacent to the valve seat, but the slot formation shown is the less expensive way of forming the opening. Of course the upper ends of the openings will communicate with the bottom of the chamber 10 of the cup portion 6, so that gasolene will run from the cup through these openings into the engine when the valve is open. The lower end of the body portion is provided with a valve seat 11 shown herein as of tapered form. The cup portion 6 is provided with an opening 12 extending at an angle to the cup chamber, but in line however with the axial passage in the body portion. This permits the use of a straight stem on the valve member proper. This valve member 18 comprises a valve portion or head 14 shown as tapered, cooperating with the seat of the body portion. It will however be understood that any form of valve seat or opening could be used so long as the valve is constructed to bear against the outer end of its seat. This valve member is also provided with an enlarged portion 15 having threads adapted to cooperate with the threads on the walls of the axial passage and a stem 16 projecting from the axial passage into and through the opening 12, and it terminates at its upper end in a bend or handle portion 17 whereby on turning'the handle the valve will be either seated or unseated from its seat. In this form it will be observed that the valve member projects as it were. from the side of the cup,the stem thereof intersecting the cup chamber.

In Figs. 2 and 3 the body portion or member is made in substantially the same manner as the body portion of the cup shown in Fig. 1, except that above the wrench-receiving portion there is formed a projecting exteriorly threaded portion 19, on which the neck 20 of the cup portion proper may be turned, the said neck portion as shown in Figs. 2 and 3 being provided with interior threads for this purpose, or if preferred the cup portion 6 may be instance brass or steel, it may be so formed or drawn as to have one side thereof curved as at 21, and thus permit the stem tO PFOWCt through the cup in line with the axial passage of the body without the necesslty of projecting the stem through the s1de of the cup, although this could be done, 1f found desirable, in the same manner that it is done in Fig. 1. In the form shown in Fig. 3 the cup portion proper 6 has the top thereof practically closed, as at 25, whlle the opening for the insertion of the fluld is at the side as at 26. The particular form shown 111 Fig. 3 is more particularly adaptedfor use when it is desired to insert the pruning and testing cup into the side of an engine.

Obviously the handle may be bent at any desired point and in the present instance it is so bent as to prevent the tapered portion of the valve from dropping away from the body when the parts are assembled or from opening beyond the deslred amount. In the use of the device, gasolene ispoured into the cup and when the valve 1s open. it runs through the slots 9 into the cylirr der of the engine. Thus it will be seen that when the valve is closed the opening into the body member of the cup at the bottom end of the device is entirely closed by the tapered valve member, so that there 18 no opportunity for the passage of carbon or soot to the cup or to interfere with the effec tive closing of the valve, or in any way interfere with the operation of the device so that there is no chance for the valve pas-- sage in the body to becomeclogged, and there is, moreover, no opportunity of one part dropping away from the other into the engine, and the priming of the engineby means of this improved cup 1s a direct priming, that is to say, the liqu d runs d1- rectly from the cup into the engine. Moreover, by reason of the formation shown the valve will always properly seat itself and thus prevent any leakage and consequent loss of power in the cylinder. In short 1n the present improvement as well as that shown in my prior patent the threads of the valve member and body so mesh that there is always a proper fit of the valve on its seat at all points around the seat and of course the stem is bent to form the handle at that particular point which will facilitate the opening of the valve the desired amount without moving the valve away from its seat an unnecessary distance.

It will of course be understood that the various details may be more or less changed without departing from the spirit or scope of the present improvement.

In all forms of the present improvement it will be observed that the opening into the cup chamber for the insertion of the gasolene or fluid is at one side of the valve stem, that is, the perpendicular axis of the opening is transverse to or inclined to the valve stem proper, whether the priming and testing cup proper be made as an integral one as shown in Fig. 1 or with a sheet metal cup portion as shown in Figs. 2 and 3.

It will be observed that the upper portion of the cup, especially that shown in Fig. 1, tapers or flares outwardly so that it is of larger diameter at this point than that portion of the cup which communicates with the axial passage 7. Obviously the formation of the cup is such that the spout of an oil can may be readily inserted thereinto and be properly guided into the cup.

From the foregoing, it will be seen that the present improvement comprises a fitting provided with a threaded nipple 4, a polygonal portion 5 and a portion beyond said polygonal portion having a lateral enlargement forming the cup 6, and that the bore 7 extends longitudinally of the fitting and terminates at its lower end in a conical valve seat 11 while the opposite end of the axial passage 7 merges into an oblique bore forming the en 6 having a flaring mouth portion and that the bore of the cup intersects the axial bore 7 above the conical valve seat so that both may be closed by a single needle valve 13, which is provided with a threaded stem 15 engaging a threaded portion of the bore 7.
